Title: High Speed Video of Sprite over NebraskaConcept: A halo followed by a spriteDetail: Images from a special, high resolution 1000 fps sensor, developed by Prof. Hans Stenbaek-Nielsen, Geophysical Institute of Alaska-Fairbanks, is used to construct a (false) color animation of a huge sprite above a mesoscale convective complex in Nebraska during the summer of 1999.
The top of the sprite is around 90 km, the tendrils reach down to around 40 km. The thin horizontal line is probably a jet contrail. The event begins with a classic halo. This has been uprezed from the original jpeg animation. Video Credit: WeatherVideoHD.TV
